1910
The Socialist International, meeting in Copenhagen, established a Women's Day, international in character, to honour the movement for women's rights and to assist in achieving universalsuffragefor women. The proposal was greeted with unanimous approval by the conference of over 100 women from 17 countries, which included the first three women elected to the Finnish parliament. No fixed date was selected for the observance.
1911
As a result of the decision taken at Copenhagen the previous year, International Women's Day was marked for the first time (19 March) in Austria, Denmark, Germany and Switzerland, where more than one million women and men attended rallies. In addition to the right to vote and to hold public office, they demanded the right to work, to vocational training and to an end to discrimination on the job.
Less than a week later, on 25 March, the tragic Triangle Fire in New York City took the lives of more than 140 working girls, most of them Italian and Jewish immigrants. This event had a significant impact on labour legislation in the United States, and the working conditions leading up to the disaster were invoked during subsequent observances of International Women's Day.
1913-1914
As part of the peace movement brewing on the eve of World War I, Russian women observed their first International Women's Day on the last Sunday in February 1913. Elsewhere in Europe, on or around 8 March of the following year, women held rallies either to protest the war or to express solidarity with their sisters.
1917
With 2 million Russian soldiers dead in the war, Russian women again chose the last Sunday in February to strike for "bread and peace". Political leaders opposed the timing of the strike, but the women went on anyway. The rest is history: Four days later the Czar was forced to abdicate and the provisional Government granted women the right to vote. That historic Sunday fell on 23 February on the Julian calendar then in use in Russia, but on 8 March on the Gregorian calendar in use elsewhere.
1975
During International Women's Year, the United Nations began celebrating 8 March as International Women's Day.
1977
In December 1977, the General Assembly adopted a resolution proclaiming a United Nations Day for Women's Rights and International Peace to be observed on any day of the year by Member States, in accordance with their historical and national traditions.
